Zothecula writes "For people who are unable to walk under their own power, exoskeletons offer what is perhaps the next-best thing. The devices not only let their users stand, but they also move their legs for them, allowing them to walk. While groups such as Berkeley Bionics, NASA, Rex Bionics, and ReWalk are all working on systems, Nashville's Vanderbilt University has just announced the development of its own exoskeleton. It is claimed to offer some important advantages over its competitors."
